Summary
Built in 1958 by the Natural Resources Conservation Service, this Earth-type dam stands at a height of 16 feet and has a storage capacity of 85 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," the dam plays a crucial role in regulating water flow and providing irrigation water for the surrounding area.
Managed by the South Dakota Department of Environment and Natural Resources, Donald Kelly Dam is subject to state regulations, inspections, and enforcement measures to ensure its safety and functionality. Despite being classified as a low hazard structure, the dam's importance in water resource management cannot be understated, especially in an area prone to fluctuations in climate patterns. With Dusty Johnson representing the area in Congress, the dam serves as a vital component in water conservation efforts and climate resilience strategies.
As a key component of the St. Paul District's water infrastructure, Donald Kelly Dam not only provides water storage but also helps mitigate potential flood risks and supports agricultural activities in the region. While its exact purposes and structural details may vary, the dam remains a critical asset in the state's water management efforts. As water resource and climate enthusiasts, understanding the role and significance of structures like Donald Kelly Dam is essential in safeguarding our natural resources and adapting to changing environmental conditions.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
